A turbocharger device for an internal combustion engine and a method for mounting a turbocharger device are described. The turbocharger device has a housing with a locating hole, in which a turbocharger shaft is mounted by two rolling element bearings. A rolling element bearing sleeve is situated between the two rolling element bearings. The rolling element bearing sleeve and hence the two rolling element bearings are fixed with the turbocharger shaft in the axial direction with the aid of two pins, which are introduced through a hole in the housing and are pressed into a groove in the rolling element bearing sleeve. During this process, the beveled tips of the pins slide along the chamfered outer edges of the groove as far as an end position, which fixes the axial position of the rolling element bearing sleeve.

Turbocharger device and method for mounting a turbocharger device

Disclosed is a turbocharger for an internal combustion engine, having a bearing housing. A turbocharger rotor is mounted to be rotatable in the bearing housing about the rotor axis of rotation of its rotor shaft, wherein a turbine wheel is arranged for conjoint rotation on the rotor shaft and in a turbine housing fixed on the bearing housing. Between the rotor shaft and the bearing housing, an oil seal for sealing the bearing housing with respect to the turbine housing is arranged between the turbine wheel and a radial bearing associated with the turbine wheel in order to seal the bearing housing with respect to the turbine housing. A predetermined breaking point is formed for the turbocharger rotor of the turbocharger which lies in a breaking point region and extends axially between the turbine wheel back and an axial end, facing the turbine wheel back, of the rotor-shaft oil seal.

Embodiments relate to a turbine for an exhaust gas turbocharger, which has a turbine housing in which are provided a first and a second flow duct that each has an inlet region and an outlet region. A self-regulating rotary slide valve, which has an adjustable flow duct closure element, is arranged in the inlet region of the flow ducts.

Turbine for an exhaust turbocharger

A method and a device for orienting an actuator of an exhaust-gas turbocharger which has an actuator that is equipped with an actuator housing and is connected to a control rod. First, an actuator holder is fastened to the compressor housing of the exhaust-gas turbocharger. Then the actuator is inserted into the actuator holder. Then the actuator is positioned within the actuator holder. Then a compensating material is introduced through an injection opening into a compensating-material receiving space which is provided in the actuator holder. Finally, the compensating material is hardened.

A securing element includes a head section and a shank. The cross-section of the shank changes in the axial direction in such a way that, by taking into account a qualitative and/or quantitative predetermined bending torque profile in the shank, the cross-section has a substantially uniform bending stress profile in the shank in relation to a securing element with a constant shank cross-section. An exhaust gas turbocharger having variable turbine geometry includes a VTG-guide vane configuration having at least one such securing element and being secured to a housing component of the exhaust gas turbocharger.
